Coherence can handle the RETRY bit using what's known as an EntryProcessor. This is a Java class which executes when an object is placed in the data grid. If a node dies while in the process of executing the EntryProcessor, the processor is guaranteed to be re-issued (since Coherence provides reliable data object storage). However, I was a bit dishonest there. Your EntryProcessor must be designed to be IDEMPOTENT. Meaning if it runs again, it should produce the same result. This can take a bit of thinking (and doing). But it's by no means difficult. > > I think that's even more dishonest than people like Intel or > > Microsoft.

I still have fun. :-) In my earlier email to Rogelio where I said I have better things to do than get the wireless driver to work, I didn't mean something corporate pointy-headed. For me, family, sleep, hobbies, TV are more fun than trying to get the wireless driver to work. Because these things are precious. _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
